Pemphigus is a general term for a group of rare autoimmune blistering skin disorders. Autoimmune disorders occur when the body's own immune system mistakenly attacks healthy tissue. The symptoms and severity associated with the various forms of pemphigus vary. All forms of pemphigus are characterized by the development of blistering eruptions on the outer layer of the skin (epidermis). In pemphigus vulgaris, lesions also develop on the mucous membranes such as those lining the inside the mouth. Mucous membranes are the thin, moist coverings of many of the body's internal surfaces. If left untreated, pemphigus will usually be fatal. The exact cause of pemphigus is unknown.
The term pemphigus is a general term for a group of related autoimmune blistering skin diseases. The two main types of pemphigus are pemphigus vulgaris and pemphigus foliaceus. Each type has subtypes. Additional disorders are sometimes classified as pemphigus including paraneoplastic pemphigus and IgA pemphigus. Some physicians consider these disorders similar, yet distinct, autoimmune blistering disorders with different causes and clinical, immunological and microscopic tissue (histological) features. Pemphigoid is a general term for a different group of skin disorders. These other disorders are discussed in the related disorders section of this report.
